Zipp 303 NSW Disc Wheelset
Ride away. Explore boundaries. Do so with speed, stability, and control. That’s the Zipp 303 NSW Disc Wheelset. Zipp’s 45mm rim depth proved ideal as a do-it-all wheels for cobbles, pavement, cyclocross, and gravel. Now add to that tubeless compatibility and options to run wider tires.
Without the constraints of rim brake caliper compatibility or brake-track requirements, our engineers were free to modify the NSW rim design to be disc-brake specific as well as to be more aerodynamically efficient and stable at the most common wind angles. For starters, the ABLC™ Sawtooth™ dimple design extends all the way to the rim’s edge. The result is greater AeroBalance™, our name for optimized aerodynamic efficiency and crosswind stability.
The 303 NSW Tubeless Disc-brake is optimized for wide tires to meet the performance needs of modern riders in search of low rolling resistance and high comfort. Additionally, our engineers carefully considered the rim-to-tire interface and how specific tire and rim widths affect aerodynamic performance. With an internal width of 21mm, the wheelset test fastest with a 28mm tire in the majority of wind angles.
Designed to be tubeless compatible, the 303 NSW Tubeless Disc brake wheels feature a rim bed made with internal ridges to lock the tire’s bead in place. A tubeless setup allows you to run lower tire pressure for more comfort while reducing the risk of pinch flats.
